The Coldplay frontman, who has been secretly seeing the Hunger Games actress, apparently fell for the pizza-eating smoker, who is nothing like clean-living actress Gwyneth, in late June and they were seen in deep conversation at the after-party for Coldplay's Royal Albert Hall gig in London last month.

A source told The Sun on Sunday newspaper: "Chris feels he's dating someone who has everything he's been missing out on in the past 11 years.

"Jennifer doesn't take herself too seriously and when she is not filming she just wants to hang out and have a good time."

According to sources, Jen and Chris have spent the last six weeks texting each other and he showed her how much she meant to him by buying her a number of gifts for her birthday on Friday.

Jennifer split from actor Nicholas Hoult after two years together earlier this year before hooking up with Chris, who split from Gwyneth, the mother of his children, in March after 11 years of marriage.

Meanwhile, Gwyneth, 41, has reportedly made her feelings clear about Glee co-creator Brad Falchuk, who she met when she guest starred on the show, and the pair are believed to have gone on a romantic weekend away together in Utah last month, after he split from his wife Suzanne, in March this year.

A source added: "Chris is a sensitive guy and it hurts him to see her moving on so quickly. They've not waged a war on each other but certainly Chris wishes she had kept things quiet."

Now it seems now she's not the only one who is moving on in attempt to find happiness with someone else.
